CD74HC93M96 Equivalent & Substitute Parts

Part Overview

The CD74HC93M96 is a 4-bit binary counter IC manufactured by Texas Instruments, housed in a 14-SOIC surface mount package. This device functions as a negative edge-triggered counter with asynchronous reset capability, operating across a wide supply voltage range of 2V to 6V and temperature range of -55°C to 125°C. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent functional performance, electrical parameters, and package compatibility are maintained across the specified operating conditions.

Substitute Part Grouping Explanation

Substitution for the CD74HC93M96 is determined by equivalence in the following critical parameters: logic function (binary counter), bit width (4-bit), trigger mechanism (negative edge), reset type (asynchronous), count rate capability (35 MHz minimum), supply voltage range (2V to 6V), operating temperature range (-55°C to 125°C), and physical package format (14-SOIC surface mount).

The CD74HC93MT represents a parametric equivalent with identical electrical and functional specifications, differing only in packaging format (Tape & Reel versus Cut Tape). This substitution is valid for applications where packaging configuration does not impose design constraints.

The 74HCT273D,653 is listed as a manufacturer-recommended alternative; however, this device is a D-type flip-flop with fundamentally different logic function, bit configuration (8-bit), trigger polarity (positive edge), and package format (20-SOIC). This part does not meet the substitution criteria for direct replacement in counter applications requiring negative edge triggering and 4-bit binary counting functionality.

Parameter Comparison

Engineering Selection Recommendations

The CD74HC93MT is the appropriate parametric equivalent for the CD74HC93M96. Both devices maintain identical electrical specifications, functional behavior, and package geometry. Selection between these two parts depends solely on packaging format requirements: the CD74HC93M96 is supplied in Cut Tape format, while the CD74HC93MT is supplied in Tape & Reel format. The CD74HC93MT is currently discontinued at DiGi Electronics, which may impact procurement availability.

The 74HCT273D,653 is not suitable as a direct substitute. This device performs a fundamentally different logic function (D-type flip-flop versus binary counter), operates with positive edge triggering (versus negative edge), provides 8-bit storage (versus 4-bit counting), and requires a narrower supply voltage range (4.5V to 5.5V versus 2V to 6V). Application of this part would require complete circuit redesign and does not constitute a valid substitution.

Frequently Asked Questions (FAQ)

Q: Can the CD74HC93MT replace the CD74HC93M96 in production?

A: Yes. The CD74HC93MT is electrically and functionally equivalent. The only difference is packaging format (Tape & Reel versus Cut Tape). Verify that your assembly process accommodates the selected packaging format.

Q: Is the 74HCT273D,653 a valid substitute?

A: No. This part is a D-type flip-flop, not a binary counter. It operates with positive edge triggering, provides 8-bit functionality, and requires 4.5V to 5.5V supply voltage. It cannot replace the CD74HC93M96 in counter applications.

Q: What are the critical parameters for substitution?

A: Valid substitutes must maintain: 4-bit binary counter function, negative edge triggering, asynchronous reset, 35 MHz count rate capability, 2V to 6V supply voltage range, -55°C to 125°C operating temperature, and 14-SOIC package format.

Q: Does packaging format affect electrical performance?

A: No. Cut Tape and Tape & Reel packaging formats contain identical die and electrical characteristics. The difference is in supply method and handling for automated assembly processes.

Q: What is the impact of the CD74HC93MT discontinuation?

A: The CD74HC93MT is discontinued at DiGi Electronics but may remain available through other distributors. For long-term supply assurance, the CD74HC93M96 in Cut Tape format is the recommended primary selection, as it maintains active production status.
